Should I get a different camper

As mentioned, make sure that you understand what you can safely tow and consider your growing family too. More people means more food, more clothes, more toys and most importantly, more weight! Plan ahead.

With that said, I would upgrade to something larger. You'll find that a LOT of people start off with tent camping and pop ups and gradually go bigger and bigger. Not too many people go out and purchase a fifth wheel right off the bat.
